FRANK BIRMINGHAM, or HORNELLSVILLE, NEW YORK.

DOOR-HANGER.

SPECIFICATION forming part of Letters Patent No. 289,961, dated December 11, 1883.

Application filed March 1, 1833. Renewed November 15, 1883. (No model.)

the following to be a full,-clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form a part of this specification.

My invention consists in the combination of devices and appliances hereinafter specified, and more particularly pointed out in the claims. I

'In the drawings, Figure 1 is a side elevation of a device embodying my invention. Fig. 2 is a front elevation of the same.

The object of myinvention is to provide an improved door-hanger, more especially designed for barn and other heavy sliding doors which are suspended upon a suitable track secured to the building. Heretofore much difficulty has been experienced in the use of doors of this class, from the liability of the supportingroller crowding'the track, producing friction, and rendering the roller and the track liable to wear unevenly. It is the special purpose of my invention to overcome these difficulties. I accomplish these results as follows:

In the drawings, A represents the door; 13, the side of the building.

0 is the track, secured in a proper manner to thebuilding and provided with an upwardlyeXtending flange.

D is the bracket of my improved doorhanger, which may be secured to the door in any proper manner as, for instance, by a suitable number of screws, a. A

E is the main roller, which supports the door upon the flange of the track 0, said roller having its bearings in the upper portion of, the bracket D, which bracket is constructed with an arm extending over and above said roller, thence extending downward, as shown,

said depending arm forming one of the bearings of the roller, and provided at its lower extremity with an inside guide-roller, 6, adapted to rotate at right angles to the roller E, its

. construction and location being such as to preat right angles to the roller E, upon the outside of the track 0, and to prevent the supporting-roller from crowding the inner edge of the track.

d is an axial arm, carrying an additional roller, 6 adapted to rotate in the same direction with the supporting-roller E, and to prevent any binding of the door upon the track. which might otherwise ensue. This roller 6 is especially designed to be employed. on smaller doors, to prevent the hanger being raised from the track when the door is started backward or forward. I would have it understood that this, however, may be dispensed with without departing from the features of myinvention, as it is evident that in the use of heavy doors there will not be the same liability. to raise the hanger from the track in shifting the door.

This hanger may be made of cast or of wrought iron, as may be desired.

What I claim is 1. A door hanger consisting of a rigid bracket adapted to be secured to the side of a door, and provided at its upper end with a dependingarm, and in connection therewith a supporting-roller journale'd to the bracket and said supporting-arm, and adapted to travel on a suitable track, an interior guide-roller journaled to the lower end of said depending arm, and an outer guide-roller journaled in the bracket, said guide-rollers adapted to roterior guide-roller journaled to the lower end of said depending arm, an exterior guideroller journaled in said bracket, said guiderollers adapted to rotate at right angles to the supporting-roller and to prevent its crowding the track, and in connection therewitha roller, 6 adapted to rotate immediately be- IOC neath the track, substantially as and for the purpose described;

In testimony whereof Isign this specification in the presence of two witnesses.

Witnesses: FRANK BIRMINGHAM.
